12 volt water pump for aquaponics manual#
You can buy it here on Reading the pump curveĮvery decent manufacturer or seller will have a pump curve in their user manual or datasheet. It’s available in paperback or eBook format. It has 265 pages filled with information about aquaponics. I have written a book that contains all the information you need to get started with aquaponics.ĭon’t be the person that makes painful mistakes during your first aquaponics build! A pump diagram with 6 different pumps listed Below you can see such a curve which is called ‘the pump curve’ which puts the relation between flow rate and head height in a nice graph. Luckily there are charts available for a pump that will indicate flowrate with a certain amount of head height. The flow rate will decrease once you are pumping water up. This means the pump will deliver 250 gallons per hour without lifting it up to your growbeds. You see, the flow rate of a pump is described with zero feet of head height (elevation). The pump tells you it’s 250 gallons per hour so it should pump 250 gallons per hour in my growbeds, right?
Let’s say you bought the 250 gallons per hour pump for your IBC system. Calculating your head height What is the head height of a pump? Now, decide what your head height will be of your system and keep that in mind for the following step. In the following image, you can see what head height really is. Less head height will require less energy consumption, which means money saved. When you are designing your system, you need to design it in a way that there is not much head height. If you are pumping from a sump to the fish tank, you can have a few feet of head height. The next question is how high you need to pump your water to whatever system you are using. If you have a DIY aquaponics IBC setup, this would mean you would need to have a pump with a rating of at least 250 gallons per hour.īut this rating alone is not enough, there is something called the head height of a pump which you need to consider as well. You will decide the flow rate of your aquaponics system by the fact that the water in your fish tank needs to be recirculated every hour. Let’s get started! What is your desired flow rate?
In this article, I’m going to teach you how you can select the right pump for your aquaponics system. One of those is selecting the right pump for your aquaponics system. When you are doing aquaponics you stumble over quite some technical difficulties.
